Welcome to Phonix
A Phonetic open source libray for .NET, no dependencies, it is pure C# code ;)
Now with support for .NET Core (thanks @ysilvestrov) and VS 2017 (thanks to @spboyer)
Latest Version
The quickest way to get the latest release of Phonix is to add it to your project using NuGet (http://nuget.org/List/Packages/Phonix).
Implemented algorithms
Today Phonix implements the following algorithms:
- Caverphone [http://en.wikipedia.org/wiki/Caverphone] - Created by David Hood, the algorithm is optimised for accents.
- Double Metaphone [http://en.wikipedia.org/wiki/Metaphone] - Phonetic encoding algorithm is the second generation of the Metaphone algorithm
- Metaphone [http://en.wikipedia.org/wiki/Metaphone] - Published by Lawrence Philips in 1990, for indexing words by their English pronunciation.
- Match Rating [http://en.wikipedia.org/wiki/Match_rating_approach] - Is a phonetic algorithm developed by Western Airlines in 1977 for the indexation and comparison of homophonous names
- Soundex [http://en.wikipedia.org/wiki/Soundex] - Is a phonetic algorithm for indexing names by sound, as pronounced in English.
How to use
Below there are examples on how to use the MatchRating, DoubleMetaphone and Soundex algorithms:
using Phonix;
public class MatchRatingApproachTests
{
private static readonly string[] Words = new[] { "Spotify", "Spotfy", "Sputfy","Sputfi" };
readonly MatchRatingApproach _generator = new MatchRatingApproach();
public void Should_Be_Similar()
{
Console.Writeline(_generator.IsSimilar(Words));
}
}
public class SoundexTests
{
private static readonly string[] Words = new[] { "Spotify", "Spotfy", "Sputfi", "Spotifi" };
private static readonly string[] Words2 = new[] { "United Air Lines", "United Aire Lines", "United Air Line" };
readonly Soundex _generator = new Soundex();
public void Should_Be_Similar()
{
Console.Writeline(_generator.IsSimilar(Words));
Console.Writeline(_generator.IsSimilar(Words2));
}
}
public class DoubleMetaphoneTests
{
private static readonly string[] Words = new[] {"Spotify", "Spotfy", "Sputfi", "Spotifi"};
private static readonly string[] Words2 = new[] { "United Air Lines", "United Aire Lines", "Unitid Air Line"};
readonly DoubleMetaphone _generator = new DoubleMetaphone();
public void Should_Return_Same_Keys()
{
string[][] keys = new string[Words.Length][];
for (int n = 0; n < Words.Length; n++)
{
keys[n] = _generator.BuildKeys(Words[n]);
}
for (int n = 0; n < Words.Length; n++)
{
for (int m = 0; m < keys[n].Length; m++)
{
if (n > 0)
{
Console.Writeline(keys[n][m], keys[n - 1][m]);
}
}
}
string[][] keys2 = new string[Words2.Length][];
for (int n = 0; n < Words2.Length; n++)
{
keys2[n] = _generator.BuildKeys(Words2[n]);
}
for (int n = 0; n < Words2.Length; n++)
{
for (int m = 0; m < keys2[n].Length; m++)
{
Console.WriteLine(keys2[n][m]);
if (n > 0)
{
Console.Writeline(keys2[n][m], keys2[n - 1][m]);
}
}
}
}
}
